299 USD;

Trimble Thunderbolt GPSDO (10MHz & 1pps), with MW power supply, antenna, and USB to RS232 cable; the phase noise of the Trimble OCXO is quite good, also the frequency stability is good, it is a good GPSDO with cheap price, the only short point is the GPSDO exist the "1024 weeks rollover" problem, if you want to get the correct month/date/year, you can use 3pv software, just like "Lady Heather", or you plus the 1024 weeks time to get the correct date.

the price is one set, the auction include:

one used Trimble Thunderbolt GPSDO;
one new Trimble GPS antenna (5 meters);
one used professional MW power, during the phase noise testing, no obvious noise appear;
one used USB to RS232 cable (FTDI chip, can download driver from FTDI web site);

ship to US 48 states in Free.

I do have several TB's , but if i were to buy another - I'd make sure it was a V3 FW.
So I would like to know if it had the "Old 2.x FW" or the latest 3.0 FW, as i seem to remember there were some issues with the 2.x FW.

The FW vers is a sticker on the "inside chip"

Ie - Here a FW 2.22

Here are pics of both FW's

Here's a "claimed" V3 - I think the APP version in Lady Heather shows the FW vers too. But since i only have V3, i have never seen LH report anything else.

Why isn't there any LH screenshots ?
